What is biodiversity?

• The loss of species globally

• The variety of living things including ecosystems, species, and genetic diversity

• The ability of organisms to adjust to environmental changes

• The concentration of toxins that aren’t degraded

What does expiration refer to in conservation biology?

• Loss of species globally

• Loss of population

• Harvesting at rates exceeding the population’s ability to rebound

• Splitting and isolating populations into patches

What is the definition of extinction?

• Loss of population

• Loss of species globally

• Competing with native species

• Connecting isolated habitats

What are invasive species known to do?

• Compete with, prey on, or parasitize native species

• Concentrate toxins that aren’t degraded

• Absorb greenhouse gases

• Split and isolate populations into patches

What is overharvesting?

• Harvesting at rates exceeding the population’s ability to rebound

• The loss of species globally

• The ability of organisms to adjust to environmental changes

• The concentration of toxins that aren’t degraded

What effect do pollutants have on ecosystems?

• They may affect ecosystems from the source and often adhere to microplastic

• They absorb greenhouse gases

• They connect isolated habitats

• They split and isolate populations into patches

What is biological magnification?

• The ability of organisms to adjust to environmental changes

• The concentration of toxins that aren’t degraded

• The loss of species globally

• The splitting and isolating of populations into patches

What does the greenhouse effect involve?

• The loss of population

• The absorption of greenhouse gases in the atmosphere and re-radiation down

• The concentration of toxins that aren’t degraded

• The splitting and isolating of populations into patches

What is phenotypic plasticity?

• The ability of organisms to adjust to environmental changes

• The loss of species globally

• The concentration of toxins that aren’t degraded

• The splitting and isolating of populations into patches

What is the goal of conservation biology?

• To understand and counter the loss of biodiversity

• To concentrate toxins that aren’t degraded

• To absorb greenhouse gases

• To split and isolate populations into patches
